石油酵母蛋白质的工业化近两、三年来引起了极大的注意。石油烃中的芳烃、稠环芳烃如苯并(a)芘、二苯并蒽、20-甲基胆蒽等毒性较高,对动物有害。要将石油酵母蛋白质作为家畜饲料或进一步作为人类食物,则对石油烃原料,石油酵母以及用石油酵母喂养的家畜体内残留的稠环芳烃等必须进行定性,定量分析,以保证安全。本文着重介绍有关苯并(a)芘的分析方法。测定苯并(a)芘一般采用萤光分析法,即先
The industrialization of oil yeast proteins has drawn great attention in the past two or three years. Aromatic hydrocarbons in petroleum hydrocarbons, condensed aromatic hydrocarbons such as benzo (a) pyrene, dibenzanthracene, 20-methylcholanthrene and other high toxicity, harmful to animals. To use petroleum yeast protein as animal feed or further as human food, qualitative and quantitative analysis of petroleum hydrocarbon feedstock, petroleum yeast, and residual PAHs in livestock fed with petroleum yeast must be carried out to ensure safety. This article focuses on the analysis of benzo (a) pyrene. Determination of benzo (a) pyrene generally used fluorescence analysis, that is, first
